Both mothers and fathers play important roles in the growth and development of children. The number and the type of parents (e.g., biological, step) in the household, as well as the relationship between the parents, are consistently linked to a child’s well-being. [1] (Nationally representative data on adoptive families are relatively new, and warrant a separate treatment.[2])
Among young children, for example, those living with no biological parents, or in single-parent households, are less likely than children with two biological parents to exhibit behavioral self-control, and more likely to be exposed to high levels of aggravated parenting, than are children living with two biological parents.[3] Children living with two married adults (biological or adoptive parents) have, in general, better health, greater access to health care, and fewer emotional or behavioral problems than children living in other types of families.[4]
Single-parent families tend to have much lower incomes than do two-parent families, while cohabiting families fall in-between. Research indicates, however, that the income differential only partially accounts for the negative effects on many areas of child and youth well-being (including health, educational attainment and assessments, behavior problems, and psychological well-being) associated with living outside of a married, two-parent family.[9],[10]
